Abstract
Halogenosilanes, e.g. Cl3SiH, are disproportionated by passing said compounds at 200-600 DEG C. over an alumina or silicon-alumina base which has been treated with a silane compound. The silane compounds used to activate the aluminaceous base are present in amounts of from 0.1 to 10 moles per litre of the solid and have the general formula R1RnSiX3-n, wherein R1 and Rn are alkyl groups having one to five carbon atoms, X is halogen, and n is 0 to 3, but when n = 3 at least one of R1 or Rn is an alkyl group. Specified silane compounds are <FORM:1027522/C1/1> The alumina or silica-alumina catalyst base is activated by drying at 400 DEG C. and subsequently passing the silane compound through the catalyst mass at 100-600 DEG C. until converted silicon compound appear in the off gas. Examples I describes the production of a mixture of Cl2SiH2 and SiCl4 from Cl3SiH.ALSO:Silicon halides are disproportionated by passing said halides at 200-600 DEG C. over a solid absorptive alumina or silica alumina base which has been treated with a silane compound of the general formula R1RnSiX(3- n) wherein R1 and Rn is hydrogen or a C1-C5 alkyl group, X is halogen and n is 0 to 3 provided that when n = 3 at least one of R1 or Rn is a C1-C5 alkyl group. The silicon halides used have the general formula alkmSiXnH4- (m+n), wherein X is halogen, alk is a C1-C5 alkyl group and m and n are each 1 to 3; their total not exceeding 4, and include Cl3SiH, CH3SiHCl2 and (CH3)3SiCl. The silane compounds used to activate the catalyst base are present in amounts of 0.1 to 10 moles per litre of solid catalyst material and include (CH3)3SiH; C2H5SiH2C3H7; (CH3)2ClSiH; CH3SiCl3; (CH3)2SiCl2 and Cl3SiH. The alumina or silica alumina base is activated by drying at 400 DEG C. and subsequently passing the silane compound at 100-600 DEG C. until converted silicon compounds appear in the off gas. The examples describe the production of mixtures containing (CH3)2SiCl2, CH3SiHCl2 an Si(CH3)4.
